IMPROVEMENT IN PLATFORM-GEARS FOR VEHICLES.

Specification forming part of Letters Patent No. 207,942, datedSeptember 10, 1878; application filed June 13, 12578.

To all whom it may concern Be it known that I, JAMES BRYANT, of Towanda,in the county of Bradford and State of Pennsylvania, have inventedcertain new and useful Improvements in Platform-Gear for Vehicles; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanyingdrawings, which form apart of this specification, and inwhich- Figure 1 is a top view. Fig. 2 is a side view, and Fig. 3 is abottom plan.

Similar letters of reference denote corresponding parts in all thefigures.

This invention relates to certain improvements in platform-sprin gs forvehicles; and it consists in the construction and arrangement of parts,which I shall now proceed more fully to describe with reference to thedrawings hereto annexed, in which--- A is the axle-bed. B B are the sidesprings, which are secured thereupon, and form inverted arches, the endsof which are curved upwardly, as shown at a a. G is a cross-frame,formed of four bars or beams, c c. D is the fifthwheel, which is securedupon the forward bolster, d, which latter is secured across the frame 0.

b b are the springs forming the end springs of my improvedplatform-gear. These are secured to the corners of the frame 0, fromwhich they extend, and they are curved and out insuch a manner thattheir ends I) b will come parallel to and in a line with the ends of thesprings B B, to which they are attached by stirrup-connections e c, theobject of which construction is to add to the strength of the springs BB. The ends of the springs I), attached to frame 0, are T-shaped, as atG, and are attached by bolts 7:, passing through the arms of the T, alsoby strips f f, crossing the springs and attached bybolts 7c. The leavesforming part of the springs b are also held in place by the cross-stripsf.

The forward spring-couplings or stirrups c e are constructed withforwardly-projecting parallel arms 6 e having eyes or apertures for thereception of screw-bolts, for the attachment thereto of the pole orthills.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- The combination, with the frame 0 Gand the springs B B, of the oblique springs b I), having the T-shapedends 0, and embraced by the strips f f, by which and fastenings k k thesprings b are fastened to the frame (J, substantially as and for thepurpose set forth.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in presence of two witnesses.

JAMES BRYANT.
